CLAIM OF PRIORITY

The present application claims priority from and is a continuation of U.S. patent application Ser. No. 11/001,676 filed on Dec. 1, 2004, the contents of which are expressly incorporated herein by reference in their entirety.

FIELD OF DISCLOSURE

The present disclosure relates generally to the management of multiple television tuners within a single location.

BACKGROUND

In order to recover television content received from a remote source, a television set top box has a television tuner. Once a particular channel is received (i.e., tuned), a user can watch the content of the channel in real time or a digital video recorder (DVR) within the set top box can record the content of the channel. As a result of this arrangement, there is an assigned tuner for each task that the set top box performs. For example, if a user wishes to watch one channel while recording another channel at the same time, the set top box would require at least two television tuners.

Television tuners are relatively expensive with respect to the total cost of a set top box, so it is beneficial to minimize the number of television tuners. During operation of a set top box, the number of desired actions may exceed the number of tuners required to perform the desired actions. In this event, the set top box will not be able to perform all of the desired actions. If a set top box includes two tuners and both tuners are assigned for use only at a single television, it is relatively easy to indicate to a user that the user's desired actions exceed the capability of the set top box. However, if multiple tuners of a set top box are assigned to different televisions in different rooms and multiple viewers are requesting actions that exceed the tuner imposed limitations of the set top box, there is increased difficulty in resolving tuner conflicts. Further, a typical home can include multiple set top boxes coupled to multiple televisions. Managing the television tuners in this environment has become increasingly difficult.

Accordingly, there is a need for an improved system and method for managing television tuners in a home entertainment system.

In a particular embodiment, each electrical outlet 110, 120 is a standard 110/120 volt alternating current (VAC) outlet. Moreover, as shown in FIG. 1, each electrical outlet 110, 120 is coupled to a power source 122, e.g., a 110/120 VAC power source. Further, each cable wall plate 106, 116 can include a coaxial cable connection, a category five (CAT-5) connection, a registered jack eleven (RJ-11) type connection, or a combination thereof. Additionally, each cable wall plate 106, 116 can be coupled to each other and to a television content source 124, such as, a digital television content source at a media provider. In a particular embodiment, the television content can be received via a cable network or a digital satellite network.

As depicted in FIG. 1, the first set top box 102 can include a processor 126 and a memory device 128 that is coupled to the processor 126. FIG. 1 further indicates that the first set top box 112 includes a first tuner 130 and a second tuner 132. The second set top box 112 also includes a processor 134 and a memory device 136. Further, the second set top box 112 includes a first tuner 138 and a second tuner 140. In a particular embodiment, within each set top box 102, 112, the processor 126, 134 can access the memory device 128, 136, for example, to write digital television content to and read digital content from the memory device 128, 136. In an illustrative embodiment, each memory device 128, 136 is a flash memory device or any other type of electronically erasable programmable read only memory (EEPROM) device or other non-volatile memory device, such as a hard disk drive. Further, each memory device 128, 136 can be a random access memory (RAM) device. In a particularly embodiment, as indicated in FIG. 1, each set top box 102, 112 includes two television tuners 130, 132, 138, 140, but each set top box 102, 112 can include more television tuners 130, 132, 138, 140. Moreover, although FIG. 1 shows that each set top box 102, 112 includes the same number of television tuners 130, 132, 138, 140 installed therein, this is not a limitation to the home entertainment system 100 shown in FIG. 1.

FIG. 1 indicates that the first power detection module 108 can include a power detection circuit 142. Also, the second power detection module 118 can include a power detection circuit 144. In a particular embodiment, each power detection circuit 142, 144 can detect when a television 104, 114 that is coupled to a power detection module 108, 118 is powered on to an operation mode or is powered down to a standby mode. In the standby mode, the television 104, 114 may receive no power or a minimal amount of power to maintain remote sensing function, clock function, or other functions that require relatively low power. An example of standby mode occurs when the television 104, 114 is turned off, but remains plugged into the electrical outlet 110, 120. In a particular embodiment, the standby mode can also occur when the television receives no power. As such, if the television 104, 114 is unplugged from the power detection module 108, 118, it would appear as if it is in standby mode.

In a particular embodiment, each power detection circuit 142, 144 can determine when a television 104, 114 is turned on or turned off by sensing current or voltage spikes at the power detection circuit 142, 144. Further, in a particular embodiment, each power detection circuit 142, 144 can operate similar to a circuit breaker. For example, when a television 104, 114 is turned on, the current at the power detection circuit 142, 144 will spike. The spike in current can cause a portion of the power detection circuit 142, 144 to move, similar to a switch in a circuit breaker. The movement of that portion of the power detection circuit 142, 144 can open a first portion of the power detection circuit 142, 144 and close a second portion of the power detection circuit 142, 144. A signal can be sent to a set top box 102, 112 that indicates that a television 104, 114 has been turned on. Alternatively, when the television is turned off 104, 114, the first portion of the power detection circuit 142, 144 can close and a signal can be sent to a set top box 102, 112 that indicates that a television 104, 114 has been turned off.

Due to the interconnection between the cable wall plates 106, 116, the power detection modules 108, 118 and the set top boxes 102, 112, the power detection modules 108, 118 can communicate with the set top boxes 102, 112 during the execution of the method described herein.

Referring now to FIG. 6, a method of managing multiple tuners in a home entertainment system is shown and commences at block 600 wherein the set top box receives a channel request for a first television tuner coupled to a first television. Next, at block 602, the set top box determines whether a recording is scheduled for the first television tuner. If a recording is not scheduled, the method continues to block 604 and the set top box changes the first television tuner channel to the requested channel. The logic then ends at state 606.

On the other hand, if a recording is scheduled for the first television tuner, the method continues to decision step 608 and the set top box determines whether a second television coupled to a second television tuner is in a standby mode. If the second television is in standby mode, the set top box transfers the scheduled recording originally assigned to the first tuner to the second television tuner at block 610. Next, at block 604, the set top box changes the first television tuner to the requested channel. At decision step 608, if the second television is not in standby mode, the set top box presents an indication, such as a display message, to a user of the first television that a recording is scheduled, at block 612.

Proceeding to block 614, the set top box indicates several options to the user of the first television. In a particular embodiment, the options include: a cancel recording option, a send recording option, and a watch recording option. Further, in a particular embodiment, the options are presented to the user via a graphical user interface presented at the first television. The options are presented via a menu and the user can navigate the menu and select an option using a remote control device. At block 616, when the set top box detects the cancel recording option, the set top box cancels the previously schedule recording. Then, at block 604, the set top box changes the first television tuner to the requested channel. The logic then ends at state 606. At block 618, when the set top box detects the selection of the watch recording option, the set top box changes the first television tuner to the channel to be recorded. The logic then ends at state 606.

Moving to block 620, when the set top box detects the send option, the set top box presents an indication at the second television, e.g., by the displaying a text or graphic message, that a scheduled recording has been transferred to the second television. Thereafter, at block 622, the set top box provides a couple of options to the second television. In a particular embodiment, the options that are indicated to a user of the second television can include a return recording option and a watch recording option. Proceeding to decision step 624, the set top box determines whether a response is received from the second television. If no response is received, indicating that no one is watching the second television, the method continues to block 626 and the set top box changes the second television tuner to the channel associated with the scheduled recording. Thereafter, at block 628, the set top box transfers the scheduled recording to the second television tuner. At block 604, the set top box then changes the first television tuner channel to the requested channel. The method then ends at state 606.

Returning to decision step 624, if the set top box receives a response from the second television, the method moves to decision step 630 and the set top box determines whether the response is the return recording option or the watch recording option. If the set top box receives the watch recording option, the method proceeds to block 626 and the set top box changes the second television tuner to the channel associated with the scheduled recording. Thereafter, at block 628, the set top box transfers the scheduled recording to the second television tuner. Then, at block 604, the set top box changes the first television tuner channel to the requested channel. The method then ends at state 606.

Returning to decision step 630, if the set top box receives the return recording option from the second television, the method continues to block 632 and the set top box presents an indication to the first television that the scheduled recording has been rejected by the second television coupled to the second tuner. Next, at block 634, the set top box presents a couple of options to a user of the first television. In a particular embodiment, the options include a cancel recording option and a watch recording option. Moving to block 616, when the set top box detects the cancel recording option, the set top box cancels the scheduled recording. Then, at block 604, the set top box changes the first tuner to the requested channel. The logic then ends at state 606. On the other hand, at block 618, when the set top box detects the watch recording option, the set top box changes the first television tuner to the channel associated with the scheduled recording. The logic then ends at state 606.

With the configuration of structure described above, the system and method of managing television tuners provides efficient management of television tuner demand based on tuner availability.
